• Performing a fuzzy search may retrieve terms with similar spellings: tu dan ve va tay hoi. hieu ve cac ((((xuc va) OR (xac va))) or (luc va)) hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu dan ve va tay hoi. hieu ve cac ((((xuc va) OR (xac va))) OR (luc va)) hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu dan ve va tay hoi. hieu ve cac ((((xuc va) OR (xac va))) or (luc va)) hanh vi cua te".
